Sumar con interfaz grafica

[flashtkd]

hola estoy estudiando Java y me gusta mucho, solo eh visto lo que es programación sin graficos ni nada, solo lineal, tipo ms-dos, la idea es poder llevar esas aplicaciones a modo grafico, con formularios, etc.

Uso el Netbeans 6.1

La idea es hacer esto:

Código:

Class Suma
 {
   Public static void main(String [] args)
    {
    int numero1, numero2, resultado;   
    resultado = numero1 + numero2;
    System.out.println (resultado);
    }
 }

Algoritmo:
resultado = numero 1 + numero;

Código:

    /** Creates new form NewJPanel */
    public NewJPanel() {
        initComponents();

private void jButton1ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
}

private void jTextField2ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
}

private void jTextField3ActionPerformed(java.awt.event.ActionEvent evt) {
// TODO add your handling code here:
}


    // Variables declaration - do not modify
    private javax.swing.JButton jButton1;
    private javax.swing.JLabel jLabel1;
    private javax.swing.JLabel jLabel2;
    private javax.swing.JLabel jLabel3;
    private javax.swing.JTextField jTextField1;
    private javax.swing.JTextField jTextField2;
    private javax.swing.JTextField jTextField3;
    // End of variables declaration

}

me imagino hacer algo como esto en el boton:

Código:

jTextField3 = jTextField1 + jTextField2;

Se agradece toda ayuda, que libro me recomiendan para crear formularios de graficos en java, saludos
